Abstract

The present invention provides a water shut off valve with a backflow prevention function which a valve seat 10 is provided at a secondary side of a valve port 6 for communicating with a primary side flow passage 3 and a secondary side flow passage 5 and a valve element 11 is detachably provided to the valve seat 10. Between the valve element 11 and the spindle 7 which freely move forward and backward in an axial line direction of the valve port 6, the valve element 11 has a spring 12 for expanding and contracting between a spindle 7 and the valve element 11 according to progress of the spindle 7.
